Probably have some debris interfering with your 'paper path'. probably one of the paper pick-up rollers- check the path, try to remove debris, and try again! blinking red led is prob. jam warning! all it takes is a little piece of paper, or other debris wrapped around a "paper feed roller' to mess things up!good luck!

I suggest you get a sheet of Card Stock (Heavy
paper) and place it in the feed way. Then press the print
button applying a slight amount of pressure on the Card Stock so it
will feed through the printer. The reason for this is in some cases I
have been able to clear the paper track of debris that was deposited there
over time.
Worth a try, as I have fixed a number of printers this
way, saving costly repairs.
Hope this helps.Bud

This machine problem can be very involved.
A paper jam as described can be in any locations of the copier.
First of all when the toner-developer falls on the base of the paper feeder, it can contanimate all paper feed shafts and even sensors, and plug connections.
Worn feed rolls can cause the machine to jam. Clean the rollers and see if it corrects the problem.
A bent paper tray can cause the copy to skew, causing jams.
Sometimes the plasic paper path baffles are warped leaving narrow gaps in the paper feed path not allowing the paper to go through properly.
A bad paper feed sensor can cause inttermittant paper feed jams. This sensor is located just above the feed rolls. A involved process to take out without breaking the plastic components.
The machine has paper feed clutches located at the back of the feed rolls. To get to them it is also involved. Sometimes these clutches slip and will cause paper feed problems. There paper feed solinoids may operate intermittantly not allowing the paper feed clutch to operate correctly.
The main board can also cause these types of problems, not allowing the correct signal to operate the paper feed solinoids.
There is so much in this area to locate and isolate for paper feed problems.
If all else fails, call Xerox for a service repair.

LED Display gives you your display visual alerts, signal strength, and operation mode. Here is an attached link for the manual.....http://www.uniden.com/pdf/LRD6399SWSom.pdfBut to answer your question here is what the difference between the green light and the red light are:1. X-Band Signal Indicator—A green LED lights and blinks toindicate the presence of an X-band radar signal. The blink rateincreases as the radar source gets closer. A distinct audio alert isalso heard. 2. K-Band Indicator— An amber (orange) LED lights and blinks toindicate the presence of a K-band radar. The blink rate increases asthe radar source gets closer. A distinct audio alert is also heard.3. Ka-SuperWideband Signal Indicator— A yellow LED lights andblinks to indicate the presence of a Ka-SuperWideband radarsignal. The blink rate increases as the radar source gets closer. Adistinct audio alert is also heard.4. Laser Signal Indicator— A red LED under L lights and blinks toindicate the presence of a laser signal. A distinct audio alert is alsoheard.5. SWS Signal Indicator— When an early warning hazard orinformational signal is detected, the yellow SWS LED begins toblink and the amber K-band LED lights. A distinct audio alert isalso heard.6. Power-On Indicator— A green LED under P lights to indicatepower is being supplied to the unit and the unit is turned on.7. LED Signal Strength Meter—Four LEDs give an accurate visualindication of the strength of radar or laser signals.8. City Mode Indicator—A green LED under C lights to indicatethat you selected City Mode.9. Auto Mute Indicator— A red LED under M lights to indicate thatyou selected the Auto Mute feature.Please make sure you give me a rating and I hope this helps,cbinny1

well, one of two things have happened, 1. you haven't removed all of the jammed paper, maybe you left a small piece of a piece of paper or you may bent or broken your paper jam sensor. go through the paper path very carefully and check both things.

I had the same problem with my Shredded. In the centre of the paper feed slot is a little sensor that detects when you put paper in, it breaks some sort of light beam that is connected to the motor circuit.

Over time paper dust gathers on this sensor, covering it completely and fooling the machine to think that there is ALWAYS a piece of paper being fed into the shredder, the result being that the motor just runs continuously.

Clear the dust from this sensor and you'll fix this particular problem - a toothbrush worked great for me - don't use it to clean your teeth afterwards :-)
